About Blogger profiles

Think of your profile as an easy way to create an "About Me" page supplemental to your blog. You can describe yourself, share your interests, include a photograph of yourself, and change your display name. Your interests, favorites, and other items act as links to other people whose profiles share the same things. Others can access your profile by clicking on your Blogger display name (i.e., when you leave a comment with your display name, or end your posts with "Posted by [display name]"), your profile widget, or by discovering your profile through shared interests.

To change your profile information, click the drop-down menu next to your username on the top-right corner of your dashboard.

From there, select Blogger profile.

Then, click the orange Edit profile button in the top-right corner. In the window that pops up, add or edit as much information as you like. Once you're finished, click Save to save your changes.
